To maximize the shelf life of your whipped cream, keep it refrigerated until ready to use and return it to the refrigerator as soon as possible. If you must leave it out, store it on ice. Storing homemade whipped cream in an airtight container will keep out contaminants and moisture. Homemade whipped cream can also be frozen for up to 2 months. An opened tub of whipped topping can be stored in the freezer for up to 4 months. Do not attempt to freeze whipped cream in an aerosol can.
